PROBLEM TO BE SOLVED: To provide a cylindrical heater structure capable of freely adjusting balance between rigidity and deformation tolerance.SOLUTION: A cylindrical heater 10 includes a graphite body 13 formed substantially in a cylindrical shape such that a heater element 12 meanders in a height direction between terminals 11 and 11, and a PBN rib 15 provided intermittently to slits 14 opened alternately in an upper end and a lower end between adjacent heater elements, and mechanically coupling the adjacent heater elements to each other. The heater has rigidity and allows deformation to some extent, so that fracture and breakage due to a difference in coefficient of thermal expansion between the graphite and the PBN rib are prevented even during use under a high-temperature condition. The heater element is prevented from flexing with its own weight when stood at a terminal part and a body to be heated can be heated having an excellent temperature distribution.

Abstract:
PROBLEM TO BE SOLVED: To provide a novel post type ceramic heater structure in which no current leakage occurs between a body base material and a heat pattern.SOLUTION: An exposed surface of a heater body 11 is insulated with a base coat 114, and then, a terminal bolt 13 is inserted in a terminal bolt insert hole 112 on the surface of the heater body. The terminal bolt is screwed in a post 12 which is housed in a post housing recess on the rear surface side, thus the post is connected and fixed to the heater body. Then, a terminal bolt head 133 is cut to be flush with the surface of the heater body, and a conductive film 116 is formed on the surface of the heater body containing a cut-out head 133'. This is partially cut out to form a heater pattern 14. Once a conductive film 123 is formed even on the outer peripheral surface of the post, it enters covering entrance paths 122 and 136 formed at the bolt and the post, for strongly connecting them together. Electrification to the heater pattern is performed through only the terminal bolt, for excellent conductive efficiency.

PROBLEM TO BE SOLVED: To provide a water support device with excellent thermal efficiency and a new structure without using screws that generate particles.SOLUTION: A wafer support device 10 comprises an electrostatic chuck 11, a thin plate member 15 and a fixing member 17. A leg part 18 of the fixing member 17 projects through an opening 16 arranged on the thin plate member above its upper face to surround a wafer location region, and an engagement part 19 projects inward from its upper end. The thin plate member and the fixing member are adsorbed and fixed to an electrostatic absorption face of the electrostatic chuck, so as to hold a peripheral edge of the wafer between the thin plate member and the engagement part of the fixing member and fix the wafer. The wafer is fixed while being held from above and below, and therefore, the wafer is not detached not only when the wafer is used in a normal upward direction, but also when it is used in a downward direction or a vertical direction.
Abstract:
PROBLEM TO BE SOLVED: To provide a new and useful technique for indicating traceability applicable to PBN products.SOLUTION: This PBN-overcoated product 4 is produced such that: after producing a body 1, at least the surface 2 of which is made from PBN, a traceability indication 2 is provided on an arbitrary site on the surface of the body with purified graphite; the surface of the body including the traceability indication is covered with PBN overcoat 3. It is preferable as a traceability-indicating technique, because sufficient transparency is given for reading a product serial number indicated on the surface of the body when the film thickness of the PBN overcoat is set as 700 μm or less. As graphite never affects the physical properties of PBN, even if the traceability indication formed by using the graphite intervenes between the body PBN surface and the PBN overcoat, functions and durability originated in the PBN product are not affected.
